This blog post applies to HoudahGeo 5. HoudahGeo 6 offers much more flexibility in handling multiple sources of altitude and heading information.
Some GPS cameras use a barometer to determine the current altitude. These cameras can write altitude information to photos even when the GPS feature is switched off. This is often seen in Panasonic cameras.
The camera creates photos that have altitude information, but lack latitude and longitude coordinates. This comes as a bit of a surprise to HoudahGeo and requires a few additional clicks on your part.
